Sunlight. Shelter it from winter frost to avoid withering of the branches and damages to the flowers.

Everyday during the vegetative season. Water it less frequently in winter, but keep the soil wet as soon as the buds grow, to avoid the fall of buds and flowers.

Every year in late winter, at the end of the blossom. Use base mould.

Prune it carefully after the fall of the flowers. Let it grow freely in summer, and then shorten the several sprouts in autumn.

By semi-wood cutting at the end of winter. By grafts in winter or in spring.
